Publication number: 20220291426Abstract: In some implementations, a diffusive optical device includes a glass substrate; a first polymer layer disposed on a first surface of the glass substrate; and a second polymer layer disposed on the first polymer layer. A refractive index of the first polymer layer may be different than a refractive index of the second polymer layer. The first surface of the glass substrate may comprise a central region and a margin region, wherein the first polymer layer is disposed on the central region and not the margin region. The first polymer layer may include a plurality of adhesion promoter molecules that causes the second polymer layer to bond to the glass substrate, wherein at least one adhesion promoter molecule, of the plurality of adhesion promoter molecules, comprises a molecularly flexible spacer.Type: ApplicationFiled: March 10, 2021Publication date: September 15, 2022Inventors: Kangning LIANG, Jaroslaw ZIEBA, Tasso SALES

Patent number: 8369678Abstract: Optical devices for guiding illumination are provided each having a body of optical material with staircase or acutely angled ramp structures on its top surface for distributing light inputted from one end of the device from the front exit faces of such structures along certain angular orientations, while at least a substantial portion of the light is totally internally reflected within the body until distributed from such front exit faces. Optical devices are also provided each have a body of optical material having a bottom surface with acutely angled ramp structures and falling structures which alternate with each other, such that light is totally internally reflected within the device until reflected by such ramp structures along the bottom surface to exit the top surface of the device or transmitted through the ramp structures to an adjacent falling structure back into the device.Type: GrantFiled: July 27, 2009Date of Patent: February 5, 2013Assignee: RPC Photonics, Inc.Inventors: Stephen H. Chakmakjian, Donald J. Schertler, Tasso Sales, G. Michael Morris

Patent number: 7918583Abstract: Lighting devices are provided for efficiently distributing light over an area to provided uniform illumination over a wide angle or other tailored illumination patterns. Each light device has at least one light source, at least one collimator for partially collimating light from the light source, and at least one diffuser for diffusing light from the collimator. The diffuser provides diffused light over an area from the diffuser having an intensity that is angularly dependent in accordance with the angular distribution intensity of light outputted from the collimator, so as to provide a predetermined illumination pattern from the device. The light sources and collimators may be provided in one or two-dimensional arrays, and a single diffuser may be formed on each collimator or the diffuser may be along a plate spaced from the collimators.Type: GrantFiled: August 16, 2006Date of Patent: April 5, 2011Assignee: RPC Photonics, Inc.Inventors: Stephen H. Chakmakjian, Donald J. Schertler, Tasso Sales, G. Michael Morris

Publication number: 20050146795Abstract: Microlens arrays (105) having high focusing efficiencies are provided. The high focusing efficiencies are achieved by accurately producing the individual microlenses making up the array at high fill factors. Arrays of positive microlenses are produced by forming a master having a concave surface-relief pattern (101) in a positive photoresist (21) using direct laser writing. Through this approach, the problems associated with the convolution of a finite laser beam with a desired profile for a microlens are overcome. The microlens arrays of the invention have focusing efficiencies of at least 75%.Type: ApplicationFiled: December 17, 2004Publication date: July 7, 2005Inventors: Geoffrey Gretton, G.
